The original name of 46th Street was Church Street, after St. Mary's Church (associated with St. Mary Cemetery). St. Mary's Church was founded in 1853 and dedicated in January 1854. The present building was dedicated on April 19, 1874. See also 45th Street, which was originally named St. Mary Street for the same church.

In 1868, Pittsburgh's modern sequence of numbered streets was created by renaming all the streets perpendicular to the Allegheny River; Church Street became 46th Street. The original renaming ordinance included Fisk Street in the list of streets to be renamed, which made Church Street 47th, but this was apparently a mistake. Less than a month later, a supplementary ordinance repealed all of the name changes east of 40th Street and redid the numbering with Fisk Street omitted, which put Church Street at 46th.
